We study the dimensions of Hadamard products of k ≥ 3 varieties if we allow to modify k − 1 of them by the action of a general projective linear transformation. We also prove that the join of a variety not contained in a coordinate hyperplane with a “nice” curve always has the expected dimension.

Abstract
We study the dimensions of Hadamard products of k ≥ 3 varieties if we allow to modify k − 1 of them by the action of a general projective linear transformation. We also prove that the join of a variety not contained in a coordinate hyperplane with a “nice” curve always has the expected dimension.File in questo prodotto:
